Effect of few-layer MoS2 flakes deposited ZnO/FTO nanorods on photoelectrochemical characteristic

We report on photoelectrochemical (PEC) characteristic of a few-layer MoS2-flakes deposited ZnO nanorod (MS-ZNR) configuration prepared via the hydrothermal and the metal-organic chemical vapor deposition (MOCVD) approach. The MS-ZNR nanostructure exhibited enhanced photoexcited electron-hole pair separation and transfer for energy-storage/or conversion applications. Due to a suppressing the recombination mechanism of charge carriers, the PEC performance of MS-ZNR photoelectrode revealed higher photocurrent density (1.42 mA.cm-2 at 0.2 V, η = 0.91%, with 0.1 M Na2S electrolyte) than a ZnO NR photoelectrode. We propose a potential application of MoS2-flakes hybrid nanostructure as enhanced efficient, inexpensive, and non-noble metal for PEC devices. © 2019 IOP Publishing Ltd.
